Trying to get my head around this.
I use a heart rate monitor in my workouts and have done a unit in advanced heart rate training and have learnt that when your heart rate is in either zone 1 or zone 2 (1 being HR low) you burn the calories from fat while if you train in zone 3 you burn carbs as your fuel source.
Is it better to train in zone 1/2 and burn less calories but the calories coming from fat?
train in zone 3 and burn lots of calories but the calories coming from carbs?
which will be the better result for weightloss?
